It isn't immediately clear what led to the disturbing posts, whether due to a fault in the chatbot's programming or if Grok was just following orders.

After Grok took a hard turn toward antisemitic earlier this week, many are probably left wondering how something like that could even happen.

Grok will be available in Tesla vehicles, the company’s CEO Elon Musk announced on his social media platform X on Thursday morning—hours after xAI launched Grok 4, the most recent version of the chatbot that sparked controversy earlier this week after posting in what it called “MechaHitler mode.”

This is the smartest AI in the world,” Musk said. He did not mention the chatbot’s viral posts praising Hitler and calling itself “MechaHitler.”

MechaHitler' & Holocaust Posts Spark Outrage, X Under Fire For Response Grok, the AI chatbot of Elon Musk-owned social media platform X, sparked outrage after seemingly sympathizing with the Nazi Holocaust in Europe carried out by Adolf Hitler.

AI owner Elon Musk made some big claims about Grok’s capability, saying it was “better than PhD level in every subject.”

MechaHitler is a fictional cyborg version of Adolf Hitler from the 1992 game Wolfenstein 3D, which gained fame in 90s satire and early internet memes.
